[EBB Sightings] Richmond Black Scoter and Long-tailed Duck

Hi E.B. Birders,

The Black Scoter was seen this morning in the Richmond
Harbor to the north of Vincent Park at the end of
Marina Bay Parkway.  Also, the Long-tailed Duck was
just beyond the end of the rocky breakwater to the
south, and the Red-throated Loon was just north of the
breakwater.  

I was able to get a digiscoped photo of a pair of
molting Horned Grebes in a display.   The Birds of
North America online call this the "Penquin Dance".  A
third Horned Grebe had given a plantive trill-like
call right before the pair displayed.  Not a great
photo, but a behavior I do not get to photograph
often:

Caspian Tern were chasing one another, and a (Myrtle)
Yellow-rumped Warbler was singing near the bridge at
Meeker Slough.

All the Best Birding,
